Abstract: The present disclosure relates to a method of making core-shell and yolk-shell nanoparticles, and to electrodes comprising the same. The core-shell and yolk-shell nanoparticles and electrodes comprising them are suitable for use in electrochemical cells, such as fluoride shuttle batteries. The shell may protect the metal core from oxidation, including in an electrochemical cell. In some embodiments, an electrochemically active structure includes a dimensionally changeable active material forming a particle that expands or contracts upon reaction with or release of fluoride ions. One or more particles are at least partially surrounded with a fluoride-conducting encapsulant and optionally one or more voids are formed between the active material and the encapsulant using sacrificial layers or selective etching. When the electrochemically active structures are used in secondary batteries, the presence of voids can accommodate dimensional changes of the active material.

Abstract: Multifunctional core@shell nanoparticles (CSNs) useful in electrochemical cells, particularly for use as an electrocatalyst material. The multifunctional CSNs comprise a catalytic core component encompassed by one or more outer shells. Also included are electrochemical cell electrodes and electrochemical cells that electrochemically convert carbon dioxide to, for example, useful fuels (e.g., synthetic fuels) or other products, and which comprise multifunctional CSNs, and methods for making the same.
